The business itself buys back the interest and retires it. This is more manageable for businesses with many owners as it only requires one insurance policy per owner rather than several reciprocal ones.

The right structure typically depends on the number of owners and tax considerations:

Owners agree on a set dollar amount. It is simple but risky because it quickly becomes outdated if not updated annually.

The business sets aside liquid assets over time.

A hybrid approach where the owners wait until a trigger event occurs to decide whether the entity or the individuals will make the purchase. Valuation Approaches

A buy-sell agreement is a legally binding contract between business co-owners that acts as a "business will," detailing how an owner's interest will be transferred or sold upon specific "triggering events" like death, disability, or retirement. It ensures business continuity by preventing outsiders from gaining control and establishing a fair, predetermined price for ownership stakes.

The remaining owners individually buy the departing owner's shares. This is simplest for small businesses with 2–3 owners and can offer tax benefits like a "step-up" in cost basis.
